BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to a solid cosmetic composition.More particularly, the present invention relates to a solid cosmeticcomposition with superior shape-retaining ability, superiorspreadability, and gloss.

[0004] 2. Description of the Related Art

[0005] In the cosmetic field, lipstick, lip-balm, foundation, pencilshaped cosmetics, and hair stick are known as solid cosmeticcompositions.

[0006] Among these, oil-based solid cosmetic compositions is (a) aliquid oil component such as caster oil, jojoba oil, squalene, lanolin,chemically synthesized ester oil, liquid paraffin, and (b) a waxcomponent which is a solidifier such as carnauba wax, candelilla wax,ceresin wax, microcrystalline wax, hydrogenated animal oil, hydrogenatedvegetable oil, beeswax, and (c) a powder component. The powder componentis dispersed in the mixture of liquid oil component and wax component.

[0007] Generally, the product must satisfy the shape-retaining abilityand usability. Usability requires especially good spreadability andgloss, which is controlled by the blending ratio of a wax component anda liquid oil component. But it is quite difficult to satisfy the demandsfor enough shape-retaining ability and good usability simultaneously.Because the wax component is an essential ingredient for solidifying theliquid oil component, it should be a large amount of the formula inorder to retain the product shape while in use and in order to allowstoring at various temperatures. When the amount of the wax component ishigh, spreadability of the product tends to be heavy, and the gloss thatis provided by the liquid oil component tends to be decreased. Becauseof this contradiction, it is difficult to satisfy the demands for enoughshape-retaining ability and good usability simultaneously. It is alsodemanded that a solid cosmetic composition have superior shape-retainingability and usability for a long period of time.

[0008] In order to solve the above-mentioned problem, a small amount ofwax giving high hardness to the product may be selected Such a waxusually has a high melting point and there is a problem that it is noteasy to produce. Such a wax requires additional heating process in orderto melt the wax ingredient at a high temperature during production andthe filling property tends to become undesirable due to the relativelyhigh melting point. Further more, when the solid cosmetic compositioncontains water such as an emulsified type lipstick, extra heating athigh temperature causes loss of the water ingredient.

BRIEF SUMMARY OF THE INVENTION

[0009] An object of the present invention is to provide a solid cosmeticcomposition, which dramatically improves the shape retaining ability andusability without an extra heating process, which avoids a problem ofthe high melting point of the wax ingredient.

[0010] The inventors conducted research to solve the aforementionedproblem and discovered that when combining a) Fischer-Tropsch wax havingaverage molecular weight of 300 to 1200 and b) Microcrystalline wax in aspecific ratio, that the liquid oil component when solidified wasunexpectedly high hardness. It was without loss of good spreadabilityand gloss and extra heating process during the production.

[0011] The present invention relates to a wax composition, which givesenough hardness to a product such as solid cosmetics, which contain aliquid oil component. The invention provides solid cosmetics havingsuperior shape-retaining ability and spreadability and gloss. Theaforementioned problem due to the high melting point of wax ingredientis eliminated.

[0013] (a) Fischer-Tropsch wax having an average molecular weight of 300to 1200 and

[0014] (b) Microcrystalline wax and (a):(b)=60:40 to 99.9:0.1 by weightratio.

[0015] The present invention relates to a solid cosmetic compositionfurther comprising a liquid oil component.

[0016] The present invention relates to a solid cosmetic compositioncomprising a solidifier consisting of wax components (a) and (b).

[0017] The present invention relates to a solid cosmetic compositionfurther comprising a colorant and/or pigment.

[0018] The present invention relates to a solid cosmetic compositionsuch as lip stick.

[0019] The present invention relates to a wax composition comprising:

[0020] (a) Fischer-Tropsch wax having average molecular weight of 300 to1200.

[0021] (b) Microcrystalline wax and (a):(b)=60:40 to 99.9:0.1 by weightratio.

BEST MODE FOR CARRYING OUT THE INVENTION

[0022] The present invention is described in detail below.

[0023] In the present invention, the ingredient (a) Fischer-Tropsch waxis a synthetic hydrocarbon wax, obtained by the “Fischer-Tropschsynthesis”, which has an average molecular weight of 300 to 1200, andpreferably 400 to 1100, and more preferably 500 to 700.

[0024] When the average molecular weight of Fischer-Tropsch wax is lessthan 300, solidability tends to be decreased. When the average molecularweight of Fischer-Tropsch wax is more than 1200, the melting point ofthe wax is too high to produce the product and extra processes arerequired. The average molecular weight in this specification iscalculated by a conventional method, and it is defined as “Mean averagemolecular weight”.

[0025] In the present invention, an average molecular weight in theabove mentioned range is necessary.. It is preferable to use aFischer-Tropsch wax having a molecular distribution curve with a sharppeak, in order to close to single distribution of the molecular range.

[0026] Fischer-Tropsch wax in the present invention is available ascommercial product. For example, commercial products having an averagemolecular weight of 300 to 1200 are as follows: “Paraflint C77”,“ParaflintC80”, “Paraflint H1” (Products of SCHUMANN SAZOL.LTD.)“FT100”, “MDP-7010” (Products of NIPPON SEIRO CO., LTD.)

[0027] The amount of the ingredient (a) is defined according to theaforementioned specific range of the ratio of ingredient (a) and (b), itis preferably 0.06 to 29.97 mass %, more preferably 0.6 to 19.98 mass %,and more preferably 3.0 to 14.98 mass % in the total solid cosmeticcomposition.

[0028] For Ingredient (b) of the present invention, microcrystalline waxis a hydrocarbon wax conventionally used in cosmetic compositions suchas lipstick, creams and the like. It uses a commercially availablematerial. It is preferable that the Microcrystalline wax have a meltingpoint which is 70° C. or more, and less than 100° C. and more preferablymore than 80 to 95° C. for best shape-retaining ability. The amount ofthe ingredient (b) Microcrystalline wax formulated in the presentinvention is 0.01 to 12 mass %, preferably 0.05 to 8 mass %, morepreferably 0.25 to 6 mass % in the total solid cosmetic composition.

[0029] In the present invention, when the wax composition, the blendedingredients (a) and (b) are in the ratio of (a):(b)=60:40 to 99.0:0.1(in mass ratio) , the composition can be used as solidifier in a solidcosmetic composition.

[0030] The blend ratio of (a) and (b) is preferably (a):(b)=80:20 to99.8:0.2 (in mass ratio), and more preferably (a):(b)=90:10 to 95:5 (inmass ratio).

[0031] When ingredients (a) and (b) are blended in aforementioned ratio,the hardness of the product has a critical point and the wax componenthas an excellent effect as solidifier.

[0032] In the present invention, the wax component is blended just bymixing ingredient (a) and (b), in the aforementioned ratios, and thepre-mixed wax component can be used for raw material for solidcosmetics. Furthermore, ingredients (a) and (b) can be separately mixedto a liquid oil component and blended into the solid cosmeticcomposition in the process of the production.

[0033] Since this wax composition gives only enough hardness to thesolid cosmetic composition, spreadability and gloss are notdeteriorated. The solid cosmetic composition containing this waxcomposition has an excellent shape-retaining ability without a problemof a high melting point in the production process.

[0034] The wax composition of the present invention has a goodsolidifier property for the liquid oil component. It has great value asa substitute material for the conventionally used solidifier such asceresin wax.

[0035] The amount of the wax composition (total amount of ingredient (a)and (b)) to total amount of the solid cosmetic composition, it isdefined according to the type of solid cosmetic composition. It ispreferably 0.1 to 30 mass % of total amount of a solid cosmetic, morepreferably 1 to 20 mass %, more particularly preferably 5 to 15 mass %to total amount of a solid cosmetic. If the blend ratio is less than 0.1mass %, the solidifier effect is not performed and the shape-retainingability of the product tends to be a problem On the other hand, if theblend ratio is more than 30 mass %, the hardness of the product of thesolid cosmetic tends to be too hard and good spreadability and glosstend to deteriorate.

[0036] In the present invention, the liquid oil component is in a liquidform at ordinary temperatures (15° C.). The oil is not limited andavailable for this invention if the oil is usable for cosmetics.

[0037] Preferably examples of the liquid oil component are as follows:

[0038] Glyceryl tri-2-ethylhexsanoate, glyceryl diisostearate,diisostearyl malate, dimethyl polysiloxane, decamethyl pentasiloxane,macademia nuts oil, trimethylolpropane trioctanoate, diglyceryltriisostearate, heptylundecyl hydroxystearate, jojoba oil, squarane,liquid lanolin, glyceryl triisostearate/hydrogenated rosinate,methylphenyl polysiloxane, glyceryl triusostearate, and polybutene.

[0039] It is particulaly preferable for lipstick compositions and othercompositions for lips, to use liquid lanolin, glyceryltriisostearate/hydrogenated rosinate, methylphenyl polysiloxane,glyceryl triisostearate, or polybutene.

[0040] It is preferable in terms of long lastingness (lasting power:staying on the skin for long time against a sebum) when it is applied tothe skin, to use volatile liquid oils (ring type silicone oils such asoctamethylcyclotetrasiloxane, decamethylcyclopentasiloxane,dodecamethylcyclohexasiloxane).

[0041] The amount of liquid oil component formulated in the presentinvention is preferably 30 to 99.9 mass %, and more preferably 50 to 59mass % in the total solid cosmetic composition,

[0042] When the amount of liquid oil component is little, spreadabilitytends to be heavy.

[0043] In the present invention of a solid cosmetic composition, inaddition to a liquid oil, if necessary, it can also be blended into asolid oil component and/or into semi-solid oil component.

[0044] In addition to the aforementioned essential ingredients, anyother ingredients, which are commonly blended in solid cosmeticcompositions, can be blended in if they do not deteriorate the effect ofthe present invention. For example: other waxes, other oils, humectants,preservatives, antioxidants, ultraviolet absorbers, ultravioletscattering agents, polymers, surface active agents, colorants, pigments,powders, drugs, alcohols, solvents, fragrances, flavors, etc, areavailable. The solid cosmetic composition of the present invention canbe produced by common production process.

[0045] In the present invention, specific examples of solid cosmeticcompositions are as follows. Make-up cosmetics such as lipstick,lip-gloss, lip balm, foundations, eye shadow, hair cosmetics such ashair stick, and pomades are examples. The solid cosmetic compositionsrefer to a broad range of compositions used for cosmetics and are notlimited to a solid cosmetic composition. A stick form solid cosmetic ispreferable, especially a lipstick containing a pigment and/or acolorant.

[0046] In the present invention, the solid cosmetic composition is insolid form at ordinary room temperature (25° C.).

[0047] The solid cosmetic composition of the present invention havingsuperior shape-retaining ability and usability is obtained by blending awax component of aforementioned ingredient (a) having particular averagemolecular weight, and the ingredient (b). Reason of the effect is notknown, but it is believed to be as follows.

[0048] The solid cosmetic composition comprising the wax component andthe liquid oil component has a network structure of a wax component inmicro crystal form, when the wax and oil are combined with each other,the liquid oil component is included in this structure and the shapestays in solid form.

[0049] The shape and size of the wax micro-crystal structure, and thetypes of the liquid oil components form the structure and character ofthe solid cosmetics. The wax composition of the present invention isbalanced to maximize the shape-retaining ability and usability bysolidifying the liquid oil component.

EXAMPLES

[0050] The present invention is described in detail below based onexamples: however, the present invention is not limited to theseExamples. The blend ratio is shown as a mass % value of the total amountof the composition unless specified otherwise.

Test of Solidification: Wax Composition

[0051] Tests were conducted on wax compositions that were mixed withingredients (a) and (b) in different blending rates and solidificationsof the liquid oils. For Ingredient (a), Fischer-Tropsch wax havingaverage molecular weight 530 (Paraflint C77 product of SCHUMANN SAZOL.LTD) was used.

[0052] Test samples (which are usable as lip gloss) were prepared bymixing 10 mass % of Wax composition (in Table 1) and 90 mass % of liquidoil (Glyceryl tri-2-ethylhexanoate). The hardness was measured by a Cardtension meter (Type No.M-301AR, Product of IIO Electric Co. Ltd).

[0053] Condition: Test samples were left under 37° C. for 1 hour,measured by 800 g load, and 3φ (diameter of a pressure sensitive shaft)at 37°C.

[0054] The test results are shown in the following Table 1.

[0055] The wax amount in Table 1 is a concentration of the wax in thewax composition.

[0056] As it is clearly indicated in Table 1, the hardness of the testsample was increased critically when the blending ratio of (a) and (b)is (a):(b)=60:40 to 99.9:0.1, preferably (a):(b)=80:20 to 99.8:0.2, andmore preferably (a):(b)=90:10 to 95:5.

[0057] When the blending ratio is in aforementioned specific range, thewax composition has a remarkable hardness. The aforementioned specificrange has critical meaning in the present invention.

[0058] It is an unexpected result that the wax composition mixed withingredients (a) and (b) in the specific ratio solidifies the liquid oilin maximum hardness. It is preferable to use the wax composition of aspecific blending ratio for obtaining a maximum hardness. Also, theaforementioned wax composition does not have any problem concerning tothe melting point during the process of production for a solid cosmetic.TABLE 1 Sample a b c d e f g h i j k l Fischer-Tropsch 100 99.9 99.8 9590 85 70 60 50 40 20 0 wax Microcrystalline 0 0.1 0.2 5 10 15 30 40 5060 80 100 wax Hardness of the 11 14.3 17.8 21.8 20.5 18.8 13.8 12 10.39.5 8.5 8 solid sample
